SPRAYING DEVICE.

T0 all 'whom it may concern.'

Be it known that I, WILLIAM T. KING, a citizen of the United States,residing at Minneapolis, in the county of Hennepin and State ofMinnesota, have invented certain new and useful Improvements in SprayingDevices; andI do hereby declare the follow- `ing to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

My invention has for its object to provide an improved spraying deviceadapted for use generally for spraying liquids, but especially adaptedfor use for spraying poisonous liquids or liquid germicides in theorchard and garden.

More particularly, the invention is designed to meet the specialrequirements of a small orchardist, gardener and fruit grower who needssomething larger than a knapsack sprayer but does 'not require anythingas large as a horse propelled or power outfit. V

The present improved sprayer is adapted to be wheeled after the plan ofa wheel barrowV and is usually provided with a tank adapted to carryabout fifteen gallons of the spraying liquid or germor fungus destroyingsolution. The pump and air chamber are carried by and located within'theliquid supply tank, and the pump is adapted to be operated `by a simplelever.

Generally stated, the invention consists of the novel devicesand`combinations of devices hereinafter described and defined in the claim.

In the accompanying drawings which illustrate thelinventio'n, likecharacters indicate like parts throughout the several views.

Referring to the drawings, Figure 1 `is a View in side elevation,showing the improved spraying apparatus; Fig. 2 is a lan view of thesame; Fig. 3 is a view chie y in vertical section, taken on the line w8w3 of Fig. 2, some parts being broken away and some parts being shown infull; and Fig. 4 is a detail in vertical section taken on the line ofFig. 3.4

The. liquid containin tank 1 is secured by hang r brackets 2 t t eintermediate .p0r-

bolt 5. In front of the tank 1, .the bars '37 tions-of a pair ofrearwardly diverging handle bars 3, to the front ends of,which a wheel 4is journaled by means of a nutted Specification of Letters Patent.

are rigidly but detachably connected by a tie bar 6, and at the rear ofsaid tank, they are likewise connected by a tie bar 7, the ends of whichtie bars are preferably bolted to the said bars.

In this improved spraying apparatus, an air chamber or reservoir isprovided, at its upper portion, with diverging legs constitutingaspider-like head which is detachably secured to the upper edge rim` ofthe tank 1. This air chamber', as shown, is made up of a cylinder 8 anda cap or hollow crown 9, to which it is rigidly secured at its upperend. The cap 9 is provided with a pair of relatively long arms 10 and arelatively short arm 11, and the ends of these arms are made hook-shapedfor engagement with a peripherally grooved reinforcing rim 12 secured tothe upper edge of the tank 1. One of the arms 10 is also shown asprovided with a set screw 13 that is engageable with the grooved rim 12,to rigidly but detachably secure the said arms and, hence, the airchamber to the liquid tank, with the main body portion of the saidchamber extending into the said tank, with its axis eccentric tothe axisof the said tank. The cap 9 is provided with an upwardly extendedportion which affords a fulcrum or pivotal support 14 for apumpoperating lever 15.

A spray discharging nipple 16 leads laterally from a discharge port 17formed in the upper portin of the cap 9. The tube 18 communicates at itsupper end with the said port 17 and at its lower end, extends nearly tothe bottom of' the cylinder 8. At its lower end, the cvlinder 8 of theair chamber or reservoiris rigidly secured to a cylinder head casting19. y This c linder head casting 19 is extended, at one si e, from thecylinder 8, and is rigidly secured to the lower end of a pump cylinder20, which pump cylinder is,

21 that is connected by a long rod 22`to the lever 15.

` A suction pipe 23 is connected, at its upper end, toifthe cylinderhead casting` 19 and, at its lower end, is shown as provided with'afflaring head 24 that islocated close to the bottom of the tankl. Theupper extremity of the 'suction ipe `23 is connected `to the lower'portion ci) the pump cylinder y at the axis of the tank 1.-

' 20,. through a 25 provided,as shown,

with a ball check valve 26. The lower ends' of thecylinders 8 `and 20.areconnected by a passage 27 having aport 28' that is normallyclosed bya ball check valve 29.' The check valves 26 and 29 coperate, underreciprocating movements of the piston' 21, to

cause a ow of liquid upward through the pipe 23 into the lower end of'the cylinder' 20, from thence into ythe cylinder 8 of the air chamberor reservoir. The liquid from the lower portion of the cylinder 8 willbel caused toiow upward through the tube 18, but air will always bestored, under greater or les's compression, in the upper portion of thesaid air chamber, so that-the sprayingv action will be continuous underreciprocating movements -of the pump piston,v

and furthermore, will force a continued discharge of spray for aconsiderable time after the pump action has been stopped.' i

The various liquids used in an apparatusl of this kind, such, forinst-ance, as the Bordeaux mixture, arsenite of lead or so-called -Imineral paints, require contlnuous agitatlon to prevent settling insolid portions.` Hence,

I provide an agitator, preferably in the form of a bifurcated agitatingblade 30,

,which, as shown, is secured to a two-part lever31 intermediatelypivoted to the pipev '23 and connected, by a link 32, to' a projection33 of the pump rod 22. As is evident, under each pump actuating movementof the Ylever 15, the agitating blade 30 will be oscillated, therebykeepingdthe liquidstirred upand preventing the settling of sediment inthe bottom of the tank..

The described `arrangement connects-the pumpto the air chamber, so thatit will be appliedin working position and removed from the tank with the'said air 4chamber and, furthermore, keeps the pump subj merged in theliquid, so that primingof thel 'pump 1s not required. The air chamber isextended both above and below thevliquid and above and below the spiderwhich supports it` from the tank, so that it may be made long and ltheprojecting portion thereof Y arranged to serve as a, fulcrum for thepump actuating lever. ByV locatingthe `air chamber eccentrlcu to theaxis 0f the tank and .with 4fthe pump cylinder concentric to the axis,ofthe. tank,the lever is best arranged i. for action. on the pump and aIlarge space lever to the piston o .cient for the purposes had in View.

What I claim is:

In a spraying device, `the combination.

with a liquid containing` tank and an air chamber .having lrelativelylong and short spider arms for securing lthe same to the upper edge rimof said tank, an upwardly extended hollow cap cast integral lwith saidarms andv terminating infan upwardly extended fulcrum lug and the saidlug havinga discharge port opening laterally thereL through, of a liquiddischarge tube con+ nected at its upper end to the said discharge portand extending downward approximately to the bottom of said air chamber,.a pump actuating lever `pivoted to the said fulcrum lug, a base castingsecured to the lower end of saidI air chamber, al pump having its'cylinder rigidly secured atv its'lower end to said base casting, asuction pipe ex' tending downward from said base casting nearly to thebottom of said tank, valved ports and passages connecting 'said suction`pipe with said pump cylinder vand the said-f` pump cylinder `with thebottom of said air rod connectngtsaid chamber, and a pump lsaid pump,thefsaid pump cylinderbeing located below the top lof saidttank anddisposedsubstantially ax1- ally of said tank andthesaid airlchamberbeing located. eccentric vto'the a'zis of said tank, and the -said `pumpllever extending from -itsf pivoted lend-midway between the long spider"arms of the said air chamber,

substantiallyv as described;

In testimony whereof ture inpresence of twov witnesses.
